Long Waits
The two mothers bonded over their relationship with their husbands, especially because both of them took their sweet time popping the big question. Famously, Prince William proposed quite late, bending the knee in October 2010 after having known Kate for a full nine years prior. They'd also been reportedly dating since around 2003, meaning William waited a full seven years before finally asking for her hand in marriage. This means that as of 2020, they have known each other for nineteen years.
